Abstract
Description
Bis heute Versterben bei Verkehrsunfällen viele Menschen, weil sie durch die auf den Sicherheitsgurt, hier besonders den Beckengurt, auftretenden Kräfte Risse von Leber und Milz erleiden. Ziel der Erfindung ist es nun, einen zusätzlichen Bremsmechanismus zu entwickeln, der gerade diese Kräfte aufnehmen kann, damit der Druck auf den Sicherheitsgurt deutlich vermindert wird.To date, many people die in traffic accidents because of the impact on them Seat belt, especially the lap belt, forces occurring cracks in the liver and spleen suffer. The aim of the invention is now to develop an additional braking mechanism which can absorb precisely these forces so that the pressure on the seat belt is clear is reduced.
Um dieses zu erreichen, muß die Beschleunigung des menschlichen Körpers nach vorne bei einem Unfall verringert werden.To achieve this, the acceleration of the human body must be forward in an accident.
Ein weiterer kritischer Punkt bei Unfällen ist es, das die Personen auf der Rücksitzbank bei Pkws oder auf den Sitzen in Bussen bei einem Unfall mit ihren Knien in die Rückenlehnen der Vordersitze gedrückt werden und so die Person auf diesen Sitzen verletzen können.Another critical point in the event of an accident is that the people in the back seat are involved Cars or on the seats in buses in an accident with their knees in the backrests of the Front seats are pressed and can injure the person in these seats.
Der Erfindung liegt der Gedanke zu Grunde, das das Sitzblech mit Sitzpolster als Bremsmechanismus genutzt werden kann, da es eine große Fläche bildet und somit dort Kräfte gut resorbiert werden können. Auch die Auflagefläche des menschlichen Oberschenkels ist eine Fläche um Kräfte aufzunehmen.The invention is based on the idea that the seat plate with seat cushion as Brake mechanism can be used because it forms a large area and therefore forces there can be well absorbed. The bearing surface of the human thigh is also an area to absorb forces.
Um Sitzblech und Sitzpolster als Bremsmechanismus zu nutzen, müssen diese beweglich mit dem Sitzrahmen verbunden sein.In order to use the seat plate and seat cushion as a brake mechanism, they have to be movable be connected to the seat frame.
Bei einem Unfall klappt nun die Vorderkante des Sitzbleches mit dem Polster begrenzt hoch, wodurch die Oberschenkel des menschlichen Körpers nicht mehr wie bisher einfach ohne Bremswirkung nach vorne rutschen, sondern gegen das hochgeklappte Sitzpolster gedrückt werden und somit ein Großteil der Beschleunigungskräfte von diesen aufgenommen werden können. In the event of an accident, the front edge of the seat panel with the upholstery folds up to a limited extent, whereby the thighs of the human body are no longer as simple as before Braking effect slide forward, but pressed against the folded up seat cushion and thus a large part of the acceleration forces are absorbed by them can.
Unter die normale die dem Sitz vorhandene Trägerschiene wird eine weitere Flachschiene (1) montiert. In dieser Flachschiene befindet sich im vorderen Teile vertikal stehende Platte (2) genau so, das die normale Trägerschiene des Sitzes nicht daran stößt. Die vertikalstehende Platte wiederum ist bei einem bestimmten Druck umklappbar. Der Umklappwinkel wird durch eine Aufnahmeplatte bestimmt. Ferner befindet sich in Richtung der Umklappung eine Feder (3), welche vorne in der Flachschiene befestigt ist.A further flat rail ( 1 ) is installed under the normal support rail that is present in the seat. In this flat rail there is a vertically standing plate ( 2 ) in the front part in such a way that the normal support rail of the seat does not come into contact with it. The vertical plate in turn can be folded over at a certain pressure. The flip angle is determined by a mounting plate. There is also a spring ( 3 ) in the direction of the folding, which is fastened at the front in the flat rail.
Ferner besteht das System aus einer Bremse (4). Diese Bremse ist z. B. eine keilförmiges Stahlstück über welchem eine Blattfeder gespannt ist. Die Bremse befindet sich im hinteren Teil des Sitzrahmens ist aber nicht mit diesem verbunden, sondern liegt mit der keilförmigen Seite in einer in der Mitte geschlitzten Steuerschiene (5), welche auf Rollen (6) im Sitzrahmen gelagert ist und nach vorne zur inneren Sitzkante geht. Die Blattfeder läuft auf diesem Steuerstück.The system also consists of a brake ( 4 ). This brake is e.g. B. a wedge-shaped piece of steel over which a leaf spring is stretched. The brake is located in the rear part of the seat frame but is not connected to it, but lies with the wedge-shaped side in a control rail ( 5 ) slotted in the middle, which is mounted on rollers ( 6 ) in the seat frame and goes forward to the inner seat edge . The leaf spring runs on this control piece.
Die Bremse ist gleichzeitig durch eine Stahlstange (7) mit der vertikalen Platte in der Flachschiene verbunden.The brake is also connected to the vertical plate in the flat rail by a steel rod ( 7 ).
Die oben genannte Steuerschiene führt zur Vorderkante des Sitzrahmens und mündet in der Unterkante eines nasenförmigen Steuerstückes (8).The above-mentioned control rail leads to the front edge of the seat frame and opens into the lower edge of a nose-shaped control piece ( 8 ).
Die obere Kante des nasenförmigen Steuerstückes ist mit der vorderen Kante des Sitzrahmens fest verbunden. Es liegt gleichzeitig in einer Aushöhlung des Sitzbleches und des Sitzpolsters. Kommt es nun zu einem Unfall schiebt sich die Sitzträgerschiene auf der Flachschiene nach vorne und drückt die vertikale Platte um. Dadurch entsteht ein Zug auf die Stahlstange zur Bremse, welche ihrerseits damit die Steuerschiene blockiert. Da der Sitzrahmen aber durch die auf ihn treffenden Kräfte weiter nach vorne beschleunigt wird, schiebt er weiter nach vorne und nimmt das nasenförmige Steuerstück mit sich. Dadurch wird dieses aufgerichtet und das Sitzblech mit dem Sitzpolster wird an seiner vorderen Kante nach oben gedrückt. Hiermit kann es jetzt die auf den menschlichen Körper einwirkende Beschleunigungskraft durch die Oberschenkelabbremsung auffangen.The top edge of the nose-shaped control piece is with the front edge of the seat frame firmly connected. It lies simultaneously in a hollow in the seat plate and the seat cushion. If there is an accident, the seat support rail will slide on the flat rail in front and pushes the vertical plate over. This creates a train on the steel rod Brake, which in turn blocks the control rail. Since the seat frame but by the If the forces impacting it are accelerated further forward, it pushes further forward and takes the nose-shaped control piece with it. This will erect this and that Seat plate with the seat cushion is pushed up on its front edge. Herewith it can now be the acceleration force acting on the human body through the Catch thigh braking.
Dieses System kann bei Sitzen in Verkehrsmitteln jeglicher Art angewendet werden, besonders aber bei PKW, Bus und LKW.This system can be applied to seats in any form of transportation, especially but for cars, buses and trucks.
Eine weitere Möglichkeit das Sitzpolster schlagartig nach oben zu klappen ist einen Airbag unter der Vorderkante des Sitzpolsters an zu bringen. Bei einem Unfall spricht wie bei anderen Airbags z. B. im Lenkrad die Sensorik an und der Airbag entfaltet sich. Hierdurch wird die Vorderkante des Sitzpolsters bis zu einem gewissen Grad nach oben geschleudert. Dieses System eignet sich besonders gut für PKW, da es eine sehr kurze Ansprechzeit hat.Another option to fold up the seat cushion suddenly is an airbag under the front edge of the seat cushion. An accident speaks like any other Airbags e.g. B. in the steering wheel, the sensors and the airbag deploys. This will make the Front edge of the seat cushion flung up to a certain degree. This System is particularly suitable for cars because it has a very short response time.
Eine dritte Möglichkeit ist unter der Sitzvorderkante eine Sprungfeder so einzubauen das sie sich bei einem Unfall löst und so der Sitz nach oben gedrückt wird. A third option is to install a spring under the front edge of the seat so that it comes loose in an accident and the seat is pushed upwards.
